  • Randomisation

    There are two components to randomisation: the generation of a random sequence, and its implementation, ideally in a way so that those entering participants into a study are not aware of the sequence (concealment of allocation).
  • Randomised controlled trial

    An experiment in which two or more interventions, possibly including a control intervention or no intervention, are compared by being randomly allocated to participants. In most trials one intervention is assigned to each individual but sometimes assignment is to defined groups of individuals (for example, in a household) or interventions are assigned within individuals (for example, in different orders or to different parts of the body).
  • Remit

    The area of authority or responsibility of an individual, group, or organisation.
  • Reporting bias

    A bias caused by only a subset of all the relevant data being available.
  • Research and Innovation for Global Health Transformation

    NIHR Research and Innovation for Global Health Transformation (RIGHT) funds cutting-edge interdisciplinary applied global health research in key areas in low and middle-income countries where a strategic and targeted investment can result in a transformative impact.
  • Research for Patient Benefit

    The NIHR Research for Patient Benefit (RfPB) programme funds health, public health and social care research to improve the lives of people with health and care needs.
  • Researcher-led

    Open calls for researchers to apply for funding for their own topics and questions. These applications are prioritised in terms of NHS or other information need in a process similar to that of the commissioned workstreams. Applications are assessed for scientific quality, feasibility and value for money.
  • Retrospective study

    A study in which the outcomes have occurred before the study commenced. Case-control studies and cohort studies can be retrospective, but randomised controlled trials never are.
  • Reviewer

    An individual with specific knowledge, experience and skills in a field of practice who undertakes an independent review of a grant application, commissioning brief or document for publication. The comments made by this independent ‘external reviewer’ are used to inform the funding decision or the preparation of a written document.
  • RfPB

    The NIHR Research for Patient Benefit (RfPB) programme funds health, public health and social care research to improve the lives of people with health and care needs.
  • RIGHT

    NIHR Research and Innovation for Global Health Transformation (RIGHT) funds cutting-edge interdisciplinary applied global health research in key areas in low and middle-income countries where a strategic and targeted investment can result in a transformative impact.
